Former Ireland and USA coach Eddie O'Sullivan has expressed an interest in filling the void that will be left by Ospreys head coach Scott Johnson at the end of the season.

The Welsh side confirmed yesterday that Johnson will part company with the region in the summer to join Scotland coach Andy Robinson's backroom staff. And O'Sullivan, who completed a second spell as coach of the USA following the recent Rugby World Cup is "definitely" interested in working with the Ospreys.

"Eddie O'Sullivan is definitely looking for a suitable job in rugby," O'Sullivan's manager John Baker told the Irish Independent. "Unlike soccer, rugby will never be a global sport and there are a limited amount of potential clubs. Is Eddie available for a position with the Ospreys? Yes he is, 100pc."

The 49-year-old Johnson, who has previously coached Wales and the USA, will become senior assistant coach to Robinson and will be on board in time for the June tour to Australia, Fiji and Samoa. His decision to seek a new challenge will bring an end to a three-year stay with the Ospreys having linked up with the Swansea-based side in April 2009.

An Ospreys spokesperson described Johnson's departure as "a huge disappointment" and said the club will now consider their options in terms of seeking a replacement before making any further comment. "He will be sadly missed by everybody," said Ospreys chief operations officer, Andrew Hore. "Informing us of his intentions at this early stage allows us to consider our next course of action and the options available as we plan for the future."
